M8-1.25 X 70mm 六角穴付きボルト | 皿頭六角ドライブ | 部分ねじ | 18/8 ステンレス鋼 (100本/パック)

The hex socket drive on these grabbed my Allen key perfectly on every single one out of the hundred, no stripped heads or rounded corners. Threads cut clean through my steel jig without any binding, and the partial threading gave just the right grip for the depth I needed.

These flat heads sit flush and clean on my fixture table, and the hex socket makes driving them into tight spots a breeze. The 18/8 stainless steel feels solid and resists rust so far, which is exactly what I needed for these tooling projects.

Used a full bag of these on a jig for a repeat drilling setup and every single one threaded smoothly without binding. The 18/8 stainless feels substantial and the flat head sits perfectly flush in counterbores. Exactly what I needed for precision work.
